Review on 🔩 ACTOOL Industrial Drill: Double Spiral for Enhanced Drilling Efficiency by Charles Adelaja

I wasn't sure how much hype to believe on these spiral step drills, but after using it to drill out a few wing washers for the screw, I have to say , that the cutting action is actually better than the standard step drill and the spiral pattern seems to pick up chips better than the standard step drill. The diameter markings are easy to read and the quality of the bit looks good. I expect the HSS material this bit is made of to last longer than typical titanium coated step bits. Although expensive compared to the standard step drill sets you can get from the port, I would expect them to last 3-4 times longer.
